Article Synopsis
- * The research involved two groups of cows: those receiving training and a control group, with behavioral observations made during post-calving, calf handling, and post-handling periods.
- * Results showed that trained cows exhibited less maternal care and protective behaviors during the first handling of their calves compared to the control group.
The aim of this study was to investigate whether parameters obtained by computer-assisted sperm analysis (CASA), infrared thermography (IRT), and testicular B-mode and Doppler ultrasound can be used as indicators of fertility in natural service Nellore bulls. Twenty-nine Nellore bulls were evaluated on days 66 (-D66), 38 (-D38), and 10 (-D10) before the beginning of natural service mating. In all assessments, semen samples were collected and sperm kinetics were evaluated by CASA, thermographic imaging of the scrotal and ocular region, testicular B-mode ultrasound, and Doppler ultrasound of the spermatic cord.

- * Researchers examined thirty-one Gyr cows to assess differences in behaviors between first-time (primiparous) and experienced (multiparous) mothers in terms of pain signs, defensiveness towards handlers, and maternal care.
- * Findings indicate that primiparous cows were more likely to show signs of pain and movement, while multiparous cows were more aggressive during calf handling; cows that nurtured their calves effectively tended to be calmer and more attentive.
Technological devices are increasingly present in livestock activities, such as identifying the reproductive status of cows. For this, predictive models must be accurate and usable in the productive context. The aims of this study were to evaluate estrus-associated changes in reticulo-rumen temperature (RRT) and activity (ACT) in Dairy Gyr heifers provided by reticulo-rumen boluses and to test the ability of different models for estrus prediction.

The aims of this study were 1) to describe the pattern of reticulo-rumen temperature and activity variation in nulliparous Gyr heifers close to calving, and 2) to evaluate the predictive potential of these traits for calving in Gyr heifers. Forty pregnant Gyr heifers that had calved between August and December 2017 at the Getúlio Vargas Experimental Station, Empresa de Pesquisa Agropecuária de Minas Gerais (Epamig), Brazil, were used.

This study investigated whether the type of cat management (indoor vs. outdoor) was related to other cat care practices adopted by cat owners, associated with the quality of human-cat relationships and cat welfare.
